Description

Technical Field

[0001] This utility model belongs to the field of mechanical equipment technology, and more specifically, it relates to a self-propelled small crane. Background Technology

[0002] In various industries such as construction and machinery manufacturing, cranes are needed to lift and transport various mechanical equipment and prefabricated building components. For some small machinery and prefabricated components, mobile cranes that can be moved at will are more practical. However, while mobile cranes are convenient for changing the site of use, if it is necessary to transport the lifted objects over a long distance at the same time, the stability of the crane during the transport of the suspended objects is insufficient, and the safety cannot be guaranteed.

[0003] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a self-propelled small crane in order to achieve a more practical value. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a self-propelled mini crane to solve the issues of insufficient stability and lack of safety guarantees in mobile cranes during the transportation of suspended objects.

[0005] The purpose and effect of this utility model of a self-propelled small crane are achieved by the following specific technical means:

[0006] A self-propelled mini crane includes a platform with a column rotatably connected to it. A bottom frame is provided at the bottom of the platform, and a movable component is provided inside the bottom frame. The column passes through the platform and is connected to a drive mechanism inside the bottom frame. A hanger is provided on the column, and an electric hoist is installed on the hanger. A notch is provided on one side of the platform, and a cover plate is hinged to the notch.

[0007] Furthermore, the platform is equipped with supports at the four corners of the bottom frame. Each support includes a support cylinder connected to the platform, a support foot passing through the bottom of the support cylinder, and a screw rod threadedly connected to the support cylinder inside the support cylinder. The bottom of the screw rod is connected to the support foot, and the top is connected to a handle.

[0008] Furthermore, a step is formed by a recess around the notch on the platform. A rotating seat is provided on one side of the step, and a rotating shaft is passed through the rotating seat. A bottom support is provided at the bottom of the cover plate and is sleeved on the rotating shaft. The other end of the cover plate is fastened to the step and covers the notch.

[0009] Furthermore, the moving component includes wheels, with the wheels rotatably mounted on the rear side of the base frame driven by a motor, and the wheels on the front side of the base frame configured as steering wheels.

[0010] Furthermore, the drive mechanism includes a steering motor, which is located at the bottom of the platform, and the output shaft of the steering motor is fitted with a gear and meshes with a gear at the end of the column.

[0011] Furthermore, the transition position of the notch connection platform is inclined as a slope.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By combining the platform and the notch, the electric hoist can lift objects onto the platform for placement and movement without requiring them to remain suspended during transport, thus improving safety. At the same time, the notch facilitates the accommodating of the lifting starting point, and the cover plate increases the area and stability of the platform for placing objects.

[0022] Example:

[0023] As attached Figure 1 To be continued Figure 3 As shown:

[0024] This utility model provides a self-propelled mini crane, including a platform 1, a column 2 rotatably connected to the platform 1, a base frame 101 at the bottom of the platform 1, and a movable component inside the base frame 101. The movable component supports the base frame 101, allowing it to travel stably on the ground. Figure 3 As shown, the moving component includes wheels 102. The wheels 102 rotatably mounted on the rear side of the base frame 101 are driven by a motor, and the wheels 102 on the front side of the base frame 101 are set as steering wheels. The motor drives the rear wheels 102 to provide transportation power.

[0025] The column 2 is rotatable. The column 2 passes through the platform 1 and is connected to the drive mechanism in the bottom frame 101. The drive mechanism includes a steering motor, which is located at the bottom of the platform 1. The output shaft of the steering motor is fitted with a gear (not shown) and meshes with the gear at the end of the column 2. This setting is conventional and will not be described in detail.

[0026] A hanger 3 is installed on the column 2, and an electric hoist 4 is installed on the hanger 3. The steering motor can drive the column 2 to rotate, thereby providing temporary hoisting function in areas outside the platform 1. The platform 1 can also place the hoisted object for long-distance transportation without having to keep it suspended during transportation, thus improving safety.

[0027] A notch 103 is provided on one side of the platform 1, and a cover plate 5 is hinged at the notch 103. The notch 103 is convenient to accommodate the hoisting starting point, and the transition position of the notch 103 connecting to the platform 1 is inclined to a slope 8, which makes it easier for the electric hoist 4 to hoist and move items to the top of the platform 1. At the same time, the cover plate 5 can increase the area and stability of the platform for placing objects.

[0028] A step 9 is formed by a recess around the notch 103 on platform 1. A pivot 104 is provided on one side of the step 9, and a pivot 105 is passed through the pivot 104. A bottom support 501 is provided at the bottom of the cover plate 5 and is fitted onto the pivot 105. The other end of the cover plate 5 is fastened to the step 9 and covers the notch 103. The step 9 can improve the support strength of the cover plate 5, thereby increasing the overall load-bearing capacity of platform 1 and cover plate 5.

[0029] In addition, brackets 6 are provided at the four corners of the bottom frame 101 of the platform 1. Each bracket 6 includes a support cylinder 601 connected to the platform 1. A support foot 602 is inserted through the bottom of the support cylinder 601. A screw rod 603 is threadedly connected to the support cylinder 601. The bottom of the screw rod 603 is connected to the support foot 602, and the top is connected to a handle. Rotating the handle can control the extension distance of the support foot 602. When the support foot 602 extends below the height of the wheel 102, the platform 1 can be stably supported on the ground. When it needs to be moved, the position of the support foot 602 needs to be shortened.

[0030] Furthermore, a reinforcing rib 7 is provided between the bottom of platform 1 and the support 6 to improve the structural strength of the support 6 when supporting platform 1.

[0031] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
